Lady Parts (TMI)

I have a question for other moms who have given birth vaginally. This is going to be super tmi but I'm 4 months post partum and I seem to have like only what I can describe as vaginal wall on the outside. It is not a prolapse of my cervix or anything like that just that spongy tissue ya know where your good spot is, well some of it is on the outside now and it gets irritated and sore and I'm just wondering if anyone else has experienced this and how to get rid of it or help it atleast
